Excellent material! Good selection of seals, got my issue resolved in 5 minutes or less after receiving this kit of parts. The delivery is fast and on time, great. A similar set, which I also ordered at the same time, is still floating around somewhere in China, obviously not only made in China but also shipped from China. Find out. I don't know when it will be here. I'm still waiting for that. TAAAAAAAAAAAAAAA if you need these things now and not in 4 weeks you need to order this. Good at everything.
